Mal:Kjemi/dok

Fra Wikipedia, den frie encyklopedi

Bruk[rediger kilde]

Malen {{kjemi}} gjør det enklere å skrive kjemiske formler. For eksempel vil {{kjemi|H|2|O}} gi: H2O

Algebraic expression as subscript[rediger kilde]

Algebraic expressions are rendered as subscripts (but must not contain upper case letters).

{{kjemi|C|''n''|H|2''n'' + 2}}

gives

CnH2n + 2

Charge[rediger kilde]

Ion charge superscripts (for: +/-) are also supported:

{{kjemi|H|3|O|+}}

yields a "+" as superscript:

H3O+

Simultaneous subscripts/superscripts are automatically handled (use a hyphen for the minus sign):

{{kjemi|SO|4|2-}}

gives "2-" as superscript:

SO2−
4
Note
The hyphen is converted to a true minus sign.

Atomic number and mass number[rediger kilde]

The first parameter can be used for mass number.

{{kjemi|4|He}}

gives:

4He

The first two parameters can be used for mass number and atomic number.

{{kjemi|4|2|He}}

gives:

4
2
He
Note
Only the first two parameters can handle two consecutive plain numbers (i.e. without a plus sign or a hyphen (+ or -) following). Otherwise the template will loop.

Linking[rediger kilde]

The optional parameter link changes the formula into a link. For example:

{{kjemi|link=vann|H|2|O}}

will yield:

H2O

For linking individual elements can be linked in the following manner.

{{kjemi|[[Hydrogen|H]]|2|[[Oksygen|O]]}} 

gives

H2O

Notes[rediger kilde]

  • To include "=" in the formula, use "=" For example, "{{kjemi|CH|2|=CH|2}}" yields CH2=CH2.
    • Or, don't use this template. For example, "CH<sub>2</sub>=CH<sub>2</sub>" yields CH2=CH2.
    • Or, {{kjemi|CH|2}}={{kjemi|CH|2}}, which yields CH2=CH2.
  • To include "≡" in the formula, use "≡" For example, "{{kjemi|HC&#8801;CH}}" yields HC≡CH.
  • The template accepts up to twenty parameters in addition to link.
  • This template uses {{su}}.
